Technology Readiness Level. An indication of the maturity of a service. Within EOSC-Future the three most relevant levels are:

TRL 7 (Beta). EC definition: "System prototype demonstration in operational environment". EOSC-Future assessment criteria:

  • Resource has passed through the development and is an advanced stage of pre-production: the software is stable, reliable and has been deployed in an operational environment   

  • Functionality as required by the target users is documented, understood, validated with target sample users and accepted by them. Internal documentation exists regarding preliminary validation tests.

  • An assessment has been made of the required load of the system once the transition into production is complete and a plan has been made to serve this load. This assessment has been documented.

  • An SLA is optional.

TRL8 (Production). EC definition:  "System complete and qualified". EOSC-Future assessment criteria:

  • There are users who are making real use of the resource and rely on it for their work.

  • Resource documentation for end-users exists and is made available.

  • An Acceptable Use Policy/Terms of Use/SLA/SLS is in place

  • Evidence that the Resource is being delivered in a way consistent with user expectations

  • Provision is made for user support, with response to incident and problem management

TRL9 (Production). EC definition:   "Actual system proven in operational environment". EOSC-Future assessment criteria:

  • All requirements of TRL 8 are met.

  • Customer feedback is gathered and documented. The Resource has been in a production state and relied upon by users for at least 1 year and evidence is provided to show this.

  • There are quantitative outputs as a direct result of resource usage.
